This notice describes the current base64.lol application. Last updated: November 3, 2026.
Browser conversion tools
Text, encoding, hash, image, media and PDF conversion inputs are processed in the browser unless a tool explicitly describes a network operation. Selecting a file for one of these local tools does not upload its contents to the application server. Page assets and required processing libraries still need network requests when they are loaded.
Tools that use the network
DNS lookups, public-IP checks, Wikipedia searches and remote-image retrieval require requests to external services. The query, target address or URL needed for that operation leaves your device. The tool identifies its purpose before you run it. Those services and the hosting network may receive connection metadata such as IP address and request time. Downloading a remote resource can also disclose your request to its provider.
Optional analytics and storage
Google Analytics 4 loads only after you allow optional analytics. It receives page visits and basic browser and device information and may set first-party analytics cookies. Query strings, URL fragments and conversion inputs are excluded from our page-view events. Advertising features and automatic interaction measurement are disabled.
Your analytics choice and interface preferences are saved in this browser. Declining keeps Google Analytics from loading. Withdrawing consent stops collection and removes its first-party analytics cookies. Browser cache, downloaded files and clipboard content follow your browser settings; the application does not save a conversion history.
Google processes analytics information under its privacy policy. For privacy questions, contact contact@base64.lol.
Your choices
Use local tools when a remote request is unnecessary. Clear the input before sharing your screen or copying a URL. Treat Base64-encoded secrets as readable secrets. Review downloaded files and your browser's clipboard or history controls when using a shared device. External links and services have their own policies.
